Let _mathInt_ be the integer value that is represented by _numberString_ in radix-_radixMV_ notation, using the letters <b>A</b> through <b>Z</b> and <b>a</b> through <b>z</b> for digits with values 10 through 35. (However, if _radixMV_ = 10 and _numberString_ contains more than 20 significant digits, every significant digit after the 20th may be replaced by a 0 digit, at the option of the implementation; and if _radixMV_ is not one of 2, 4, 8, 10, 16, or 32, then _mathInt_ may be an implementation-approximated integer representing the integer value denoted by _numberString_ in radix-_radixMV_ notation.)
